0F62791 WD Ultrastar DC HC580 22TB SAS 512 MB 3.5" Server HDD

High-Density 3.5in Enterprise SAS HDD featuring CMR bulk storage architecture with the 0F62791

The 0F62791 is a WD Ultrastar DC HC580 22TB internal enterprise HDD engineered for scale-out and always-on data centre storage tiers. Built on a helium-filled 3.5in platform, the 0F62791 targets capacity expansion where predictable latency, sustained throughput, and long service life matter more than burst performance.

Designed around a 12Gb/s SAS interface, the 0F62791 integrates cleanly into dual-port enterprise backplanes and controller architectures common in SAN/NAS back-end shelves and RAID arrays. CMR recording at 7200 RPM supports consistent rebuild behaviour and stable write performance under mixed workloads, while 4Kn with 512e emulation simplifies migration in environments standardised on 512e. A 512MB cache helps absorb command queuing and sequential stream variability, optimising large object and backup ingestion patterns. Security and data integrity features such as Secure Erase and power-loss protection align the 0F62791 with operational requirements for controlled decommissioning and resilient write completion.

Why Choose the 0F62791?

The 0F62791 delivers a strong density-to-slot profile for storage nodes where rack space, controller ports, and power budgets constrain growth. With an enterprise reliability target of 2.5M hours MTBF and design intent for 24/7 duty cycles, the 0F62791 supports predictable fleet scaling, simplified sparing strategy, and consistent behaviour in multi-drive enclosures during RAID expansion and rebuild events.

WD’s Ultrastar engineering focuses on data centre qualification, sustained thermal and vibration tolerance, and firmware behaviour tuned for enterprise SAS domains. This approach positions the platform for integration with modern storage standards, including large-capacity tiers, automated lifecycle management, and secure operational processes.

Key Applications:

• Scale-out and object storage nodes
• RAID arrays and JBOD expansion shelves
• SAN/NAS back-end capacity tiers
• Backup, archive, and data lake repositories
• Virtualisation and private cloud bulk storage
